What is this mysterious Mercedes CL-Class prototype recently caught disguised? Quad exhausts and other telltale accoutrements prophisize AMG hardware to come. Could it be a CL65, with twin-turbo V12 producing in the neighborhood of 600+ horsepower? Or could it be a simple Edition series CL63, with its requisite factory kitting? No, we haven't a clue.
